BACKGROUND Recent technical developments with high-resolution real-time 3 dimensional echocardiography (RT3DE) facilitate the acquisition of high quality images and the analysis of segmental volume-time curves (VTCs). AIMS To assess left ventricular (LV) asynchrony using the VTCs of 16 segments by RT3DE, and to evaluate accuracy compared to tissue Doppler(More)
AIM This study was done to explore the 3D geometry of the normal tricuspid annulus and compare it with the mitral annulus (MA), using real-time 3D echocardiography (RT3DE) and newly developed 3D computer software. METHODS Thirteen left ventricular (LV) and 13 right ventricular (RV) volumetric images were obtained using RT3DE from normal subjects. LV and(More)
This study was conducted to explore the geometrical changes of the mitral annulus during systole. The 3D shape of the mitral annulus was reconstructed in 13 normal subjects who had normal structure of the mitral apparatus using real-time 3D echocardiography (RT3DE) and 3D computer software. The two orthogonal (antero-posterior and commissure-commissure)(More)
A 67-year-old male patient was admitted with an abrupt sudden cardiac death. He represented with an extreme electrical storm of 30 times of ventricular fibrillation (VF) episodes on one day. External shocks were performed to terminate VF. Transient J-wave in the inferior-lateral leads and Brugada electrocardiography pattern on the right precordial leads(More)
The post cardiac injury syndrome is characterized by the development of a fever, pleuropericarditis, and parenchymal pulmonary infiltrates in the weeks following trauma to the pericardium or myocardium. According to previous reports, almost all cases develop after major cardiac surgery or a myocardial infarction. Recently, a few reports have described post(More)
RATIONALE Recurrent ventricular arrhythmias after initial successful defibrillation are associated with poor clinical outcome. OBJECTIVE We tested the hypothesis that postshock arrhythmias occur because of spontaneous sarcoplasmic reticulum Ca release, delayed afterdepolarization (DAD), and triggered activity (TA) from tissues with high sensitivity of(More)
AIMS We aimed to investigate whether thrombus aspiration could preserve the index of microcirculatory resistance (IMR) after primary percutaneous coronary intervention (PCI) in patients with ST-elevation myocardial infarction (STEMI). METHODS AND RESULTS Sixty-three patients with STEMI were randomised into two groups: primary PCI after thrombus aspiration(More)
BACKGROUND Although prompt reperfusion treatment restores normal epicardial flow, microvascular dysfunction may persist in some patients with acute coronary syndrome (ACS). Impaired myocardial perfusion is caused by intraluminal platelets, fibrin thrombi and neutrophil plugging; antiplatelet agents play a significant role in terms of protecting against(More)
BACKGROUND AND OBJECTIVES We evaluated the utility of two-dimensional (2D) and three-dimensional (3D) left ventricular (LV) global myocardial deformity parameters for assessing LV diastolic function by comparing invasive measures of LV performance. SUBJECTS AND METHODS Echocardiography and LV pressure were assessed in 39 patients. Myocardial LV(More)
BACKGROUND Bariatric surgery is being considered as a therapeutic option for morbidly obese patients. Data are accumulating showing that this surgical intervention may improve in major cardiovascular morbidity and mortality. We evaluated the effects of bariatric surgery on left ventricular (LV) structure and function including LV mechanics in obese(More)
